Abstract

一种多透镜入光面导光板，包括导光板和滚筒，所述滚筒表面设有多个凸起球面，通过加热滚筒将其表面的凸起球面转印到导光板入光面，从而在导光板入光面形成多个凹透镜。本实用新型结构简单，LED光源射出的光线通过凹透镜扩散开，增大出射角度,达到均匀出光，从而使背光源入光部画面柔和。

Description

一种多透镜入光面导光板
技术领域
本实用新型涉及一种侧入光式背光源用的导光板，具体为一种多透镜入光面导光板。
背景技术
传统的侧入光式背光源用的导光板，其入光面为镜面抛光加工，LED发光处亮度较两颗LED之间处高，造成背光源入光部有亮暗不均的现象，俗称“萤火虫”现象。如图1所示，LED光源2射出的光线3射到入光面为镜面抛光加工的导光板1上，出射角较小，射出的光线只在LED光源2正上方的导光板1射出，导致背光源入光部有亮暗不均的现象。
实用新型内容
本实用新型所解决的技术问题在于提供一种多透镜入光面导光板，以解决上述背景技术中提出的问题。
本实用新型所解决的技术问题采用以下技术方案来实现：
一种多透镜入光面导光板，包括导光板和滚筒，所述滚筒表面设有多个凸起球面，通过加热滚筒将其表面的凸起球面转印到导光板入光面，从而在导光板入光面形成多个凹透镜，导光板上的凹透镜将LED光源射出的光线扩散开，增大出射角度,达到均匀出光，从而使背光源入光部画面柔和。
进一步的，所述凹透镜之间的间距为0.1um～3.0cm，凹透镜的深度为0.05um～1.0cm。
本实用新型的有益效果为：本实用新型结构简单，LED光源射出的光线通过凹透镜扩散开，增大出射角度,达到均匀出光，从而使背光源入光部画面柔和。
附图说明
图1为现有技术的结构示意图；
图2为本实用新型导光板的结构示意图；
图3为本实用新型滚筒的结构示意图。
具体实施方式
为了使本实用新型的实现技术手段、创作特征、达成目的与功效易于明白了解，下面结合具体图示，进一步阐述本实用新型。
如图2、图3所示，一种多透镜入光面导光板，包括导光板1和滚筒4，所述滚筒4表面设有多个凸起球面5，通过加热滚筒4将其表面的凸起球面5转印到导光板1入光面，从而在导光板1入光面形成多个凹透镜6，导光板1上的凹透镜5将LED光源2射出的光线3扩散开，增大出射角度,达到均匀出光，从而使背光源入光部画面柔和。
以上显示和描述了本实用新型的基本原理和主要特征和本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本实用新型的原理，在不脱离本实用新型精神和范围的前提下，本实用新型还会有各种变化和改进，这些变化和改进都落入要求保护的本实用新型范围内。本实用新型的要求保护范围由所附的权利要求书及其等效物界定。
